TYPE-BAR FOR TYPE-WRITERS OR LIKE MACHINES- SPECIFICATION forming partof Letters Patent No. 774,925, dated November 15, 1904. Applicationfiled February 2, 1904. Serial No. 191,654. (No model- To alt 10/2/0177,it may concern:

Be it known that I, FRANZ X. WAGNER, a citizen of the United States,residing in the borough of the Bronx, city, county, and State of NewYork, have invented certain new and useful Improvements in Type-Bars forType- VVriters or Like Machines, of which the following is aspecification.

My invention relates to type-bars for typewriters or like machines, andhas for its object to provide a simple and eflicient device to permit ofthe removal of the type-bars from the segment or other support.

Reference is to be had to the accompanying drawings, in which-- Figure 1is a diagrammatic sectional view of a portion of a type-writer,illustrating my improved type-bar; and Fig. 2 is an end view of the saidtype-bar looking in the direction of the arrow in Fig. 1.

A is the segment, fastened to the frame of the machine in the usual wayand provided with slots A, open at the top and bottom.

B is the rod upon which all the type-bars are pivoted and which extendsthrough the entire segment. It will be understood that the slots A ofthe segment are arranged in a semicircle. Upon the rod B are hung thetype-bars O, the said type-bars being provided with a seat B forengaging the rod B and an open-endpassage leading from said seat andhaving the type D and arranged to print upon paper carried by the platenD. The typebars G are connected, through the medium of a link E, by apin-and-slot connection, as at E, to an elbow-lever fulcrumed upon theframe of the machine at G. The said elbow-lever F in turn has apin-and-slot connection with keylever H, pivoted at H upon the frame ofthe machine and carrying the usual key H I is a spring which tends tokeep the keylevers in their normal position, and I is a cushion or padupon Which the type-bars rest when in their lower position.

The type-bars of my invention are each provided with a projection J,upon which is pivoted at K an elbow-lever K, one arm of which, K forms ahandle, and the other arm of which extends upward from the pivot K, theupper end terminating just below the pivot-bar B, thus formingpractically a complete eye for the pivot below the pivot-bar B. Theelbowlever K is further provided with a lug L and is held in its normalor locked position by a spring M. Thus when the elbow-lever K is in theposition shown by solid lines in Fig. l the type is prevented fromleaving the pivotbar B no matter in what position the type-bar may be.If now for any reason the operator wishes to remove the type-bar fromthe segment, all that is necessary is to press the handle K of theelbow-lever K to the position shown in dotted lines in Fig. 1, theupwardextending arm of the elbow-lever K having by this operation beenthrown from underneath the rod B, whereupon the type-bar C may bereadily lifted until the lug L comes in contact with'the pivot-rod B andthe link E is disengaged from the elbow-lever F, the type-bar being thendrawn forward and free of the slot A. The purpose of the lug L is to actas a stop to prevent the type-bar from being lifted too high and thespring M from striking the lower surface of the segment. In replacingthe type-bar it is only necessary to push it into the slot, theelbow-lever moving against the tension of the spring M, guiding thetype-bar to the pivot, and then snapping back into place beneath thepivot-rod B and again securely holding the type-bar to prevent it fromleaving the said pivot-rod B.

Various modifications may be made without departing from the spirit ofmy invention.

1 claim as my invention and desire to secure by. Letters Patent 1. In atype-writer or like machine, a support, a pivot carried by said support,a typebar provided with a seat adapted to engage said pivot, and anopen-end passage leading from said seat, and a device movably carried bysaid type-bar and arranged in its normal position to close the saidpassage of the typebar, said device being movable to a position in whichit leaves said passage open to permit the type-bar to be removed fromthe pivot.

2. In a type-writer or like machine, a support, type-bars pivoted onsaid support and a device movably carried by the type-bars,

which in one position secures the same against removal from the supportand in another position permits the said type-bars to be removed fromsaid support.

3. In a type-writer or like machine, a sup port, type-bars pivoted onsaid support, a movable device carried by each of the typebars, which inone position locks the same against removal from the support and inanother position permits the said type-bars to be removed from thesupport and means for normally keeping the said device in its lockingposition.

4. In a type-writer or like machine, a support, a type-bar pivoted onsaid support and provided with a projection, a device pivoted on saidprojection for locking the type-bar against removal from its pivot, andmeans for keeping said device in its locking position.

5. In a type-writer or like macl1ine, a support, a type-bar pivotallycarried by said support and provided with a projection, a locking devicefulcrumed on said projection and arranged while in its normal positionto secure the type-bars against removal from the support and means forthrowing the locking device into an abnormal position to permit of thetype-bars being removed from the support.

6. In a type-writer or like machine, a support, a type-bar fulcrumedupon said support and provided with a projection, a locking devicepivoted on said projection and arranged while in its normal position tosecure the typebars against removal from the support, means for throwingthe said locking device into an abnormal position to permit of thetype-bars being removed from the support and a spring for normallykeeping the said device in its locking position.

7. In a type-writer or like machine, a support provided with slots,apivot-rod extending through said slots, type-bars in said slots andfulerumed on said pivot rod, a movable locking device carried by saidtype-bars, comprising an arm arranged below the pivot-rod and adapted toprevent the removal of the typebars from the pivot-rod and a handle forthrowing the said arm from under the pivot-rod to permit the removal ofthe type-bars from the pivot-rod.

8. In a type-writer or like machine, a support provided with slots,type-bars fulcrumed in said slots, a device for holding the type-barsagainst removal from the slots when in one position, means for throwingthe device into another position to permit the lifting of the type-barsout of the slots, and a lug on said device for limiting the upwardmovement of the type-bars.

9. In a type-writer or like machine, a support provided with slots,type-bars fulcrumed in said slots, and a device carried by the typebarswhich in one position secures the typebars against removal from theslots and in a second position permits the removal of the type-bars fromthe slots and which further serves to guide the type-bars to theirfulcrum when the said type-bars are reinserted in the slots.

10. In a type-writer or like machine, a support, type-bars pivotallycarried by said support, an elbow-lever fulcrumed on each typebar, onearm of which acts as a locking device, the other arm serving as a meansfor throwing the first-mentioned arm out of its locking position and aspring for keeping said first-mentioned arm in its locking position.

11. In a type-writer or like machine, a support, a type-bar pivoted onsaid support, a locking device pivoted on said type-bar and adapted inone position to lock the type-bar against removal from the support andin another position to permit of its removal from the support.

12. In a type-writer or like machine, a support, a pivot carried by saidsupport, atypebar provided with an opening adapted to receive saidpivot, and a device movably carried by said type-bar, and adapted in oneposition to close the opening of said type-bar and in another positionto leave the same open to permit of the removal of the type-bar from thepivot.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
